Jenkins将环境变量作为参数传递

我正在为我们的内部应用程序准备性能测试脚本（gatling）。此性能测试脚本在许多Jenkins代理（~7个Jenkins代理）上执行

我想将所有与应用程序/gatling相关的环境变量作为Jenkins参数传递给Jenkins管道。然后，应用程序/gatling可以读取环境变量，并根据作为Jenkins参数提供的环境变量执行性能测试

我的代码：

pipeline {
agent { node { label 'performance-test-agents-1' } }

    parameters {
    string(defaultValue: "https://rems-xxxxxxxxxx.dev-xxx-xxx.xx.xx.local", description: "please provide the base url for target environment", name: "Baseurl")
    string(defaultValue: "10", description: "set the execution duration", name: "duration")
    string(defaultValue: "20", description: "set the qps value for throttling", name: "maxqps")
    string(defaultValue: "10", description: "set the initial concurrent users", name: "initUsers")
    string(defaultValue: "20", description: "set the ramping user count", name: "rampUsers")
    booleanParam(defaultValue: false, description: 'Update pipeline parameters without building/deploying', name: 'update_params_only')
    }

    environment {
      DURATION   = "${duration}"
      MAXQPS     = "${maxqps}"
      INITUSERS  = "${initUsers}"
      RAMPUSERS  = "${rampUsers}"
      DIRECT_LOGGINGAPI_URL = "${Baseurl}"
      ONLY_UPDATE_PARAM = "${update_params_only}"
   }

我得到的错误是：

完成：失败

您需要在声明性管道中包含如下参数。DURATION=“${params.DURATION}”MAXQPS=“${params.MAXQPS}”或您可以直接在Jenkins文件中的任何位置使用“${params.DURATION}”。要添加到@vijay的答案中，您可能需要手动将params复制到环境中，例如，

for（param in params）{env[param.key]=param.value}

。请记住，布尔参数（

true

，

false

）将转换为字符串（

“true”

，

“false”

）。@MaratC你们两个都错了。Jenkins使参数作为常规Groovy变量和环境变量自动可用。代码示例可以工作，但缺少了实际失败的部分：“at WorkflowScript.run（WorkflowScript:39）”您可以发布代码中失败的部分吗？你的参数和环境块都很好。嗨，Vijay，MaratC谢谢你的回复，答案解决了我的问题。嗨@zett42谢谢你的回复。请你详细说明一下评论好吗。对不起，我是詹金斯管道的新手
